/*
 * Colour roles follow the data-viz reference palette. Status colours are fixed
 * and never themed, and never carry meaning alone -- every badge pairs its
 * colour with a glyph and a word.
 *
 * Dark values are declared under two scopes on purpose: the media query covers
 * the OS setting, the [data-theme] scope covers the explicit toggle, and the
 * toggle has to win both ways.
